In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal and the target, the effect of the environment on the transmission of the signal, methods used to amplify the optical signal, and materials which are used to focus on and collect the optical signal are all important aspects of optical sensors. This report addresses the simulation model for the optical sensing and the configurations of the sensing elements. For this model, the simulation software Comsol Multiphysics® V5.2 is used. Using Comsol Multiphysics ® gives the advantage of building the model and applying the concepts with the help of inbuilt physics.

1. Introduction

In general an optical sensor basically is like any other device which could converts light rays(laser beams) into electronic signals, into a form ie readable. Fiber optic sensors have numerous advantages over other conventional electronic sensors. Some important advantages are as below
• Ability to integrate different structure.
• Their inability to conduct electric current.…
